As an uncle of Emperor Cassius, Duke Hubble was a nobleman who had the most extensive political connections in central politics. The late Marquis Chester, who served as Cassius's tool, earned credit by participating in the Lennox war. Grand Duke Christopher, who was Cassius's brother, was the youngest among them, but he was from the royal family who had no comparison in terms of royal bloodline and character.
"The Grand Duke was the most likely candidate among the three in terms of cause. Lennox at that time was ruled by Bertrand, so it was natural that as the same grand duke as Bertrand, Christoper was the legitimate successor."
"However… I understand he has been with the Eluang Knights since the late emperor's days. Did he reject Lennox back then?"
